NEM (XEM) Official Thread - 100% New Code - Easy To Use APIs

[mill0601]

I watched the same thing happen to medditeranean coin. It was a really unique and promising coin but the dev stopped doing anything so the coin died. It filled a great void of what to do with your old asics when they were no longer profitable to mine bitcoin, you could pair it with a cou and mine med.

[jadedjack]

But if I didnt have so much free time I couldnt be on here as much. I am actually suprised there isnt more people ticked off at the lack of anything happening. Maybe there just being silent.

It seems that you have this idea that the people here owe you something. They do not.

Sure they do. They wanted me to invest in their coin. I will leave here if someone buys my 48million at 50 satoshi each.

Unless you dont believe they are worth that

No they don't. There are no guarantees in speculation. If you were really concerned about your investment you would stop bad mouthing it in a public forum and do something positive.

Difference of opinion I guess

I would also like to introduce the NEM vanity address generator.  Would you like to have an address with you name in it?  If so, here is how to do it. 

1) download  http://blockexplore.in/static/nemGenVanity.zip

2) unzip to your desktop

3) open a command prompt and type cd Desktop/nemGenVanity

4) then type java genacc

5) pick the target that you would like in your address

Three letter words should come really fast, four letter still quickly, five letter words might take a some minutes, six letter words might take some hours, and seven letter words will take days. 

I want to run it on my VPS. Is there a command to save the result of the generator into a txt-file so I can shutdown putty and look in some days for the result on my VPS?

Hi
you can use

Code:

nohup java genacc <<< "punkrock" >> result.txt &

Use CTRL C to escape and return to the terminal, it will keep running until you kill it. The result will be in result.txt

Please compare the ranking of NEM in http://coinmarketcap.com/ and https://www.coingecko.com/en

It shows NEM is more than its mere market cap.
I am sure you will know its meaning. 

[starfishi]

sell, sell, SELL ! !

[jadedjack]

Doesn't seem to work. It creates a result.txt but it cointains only "Enter your target:"

It works, when it is finished it will add the keys to the text below "Enter your target:"

Try something simple to test it, like

Code:

java genacc <<< "test" >> result.txt

You should get that result in a few seconds

If I was you I would be more worried that Polo shuts down and runs away with your coins 
Sorry but that's way too much to have in an exchange. I learned my lesson from Mintpal.

I don't understand why, every now and then, collective hysteria explodes in this discussion.

It's all about communication. The NEM-team should be better at this. There has to be one source (for example the twitter-account) where every update needs to be posted.
Every day some update, if there is a little one. If the team delivered 22 stakes there needs to be more than a simple line in the troll-box at the NEM-forum by makoto.
If you want that people stay with NEM, let them know what's happening - every day, every little update that might be interesting for some of us. For this I would recommend Twitter / Facebook.
That's not that hard to realize with a team of 70. It's all about communication and coordination!

Here is the Twitter.  https://twitter.com/NEMofficial

The biggest and most important updates are listed on the blog.  Twitter, Facebook, BTT, and the Forum usually also share those posts too. 

In the last week, Makoto went to a conference to represent and speak about NEM.

Devs were busy working on a white paper. 

A new/updated NEM video was released and posted on the website and overview. 

NEM community rallied to take 2nd place in a vote for Liberland, and i still sneaking up on BTC.

Some new stakes were released.

The week before there were a couple of auctions to pay for the NEM mobile app for Android and iPhone.  There were other things but like a new paper wallet and vanity generator being released.  One Nemester built a new block explorer.  http://blockexplore.in/  (Still in development but already has some cool features in it)  And more things but they slip my mind.   

And there are more things too that are being worked on too behind the scenes, and when those projects are finished or close to being finished they will be announced. 

Until then, please know everybody is busy. 

I completley agree!
We need a better place to hang out than here on BCT! lol

What's the difference between

Code:

nohup java genacc <<< "test" >> result.txt &

and

Code:

java genacc <<< "test" >> result.txt

When do I use which command? The first command seems to work (Amazon's EC2 seems to be very slow on this).

The first example will allow it to run in the background without keeping a terminal open.
The second runs it in the foreground so you can see what happens

[jadedjack]

There are people on Telegram. It gets a few hundred posts a day. Then there is the nem forum. https://forum.ournem.com/
A lot of people interested in crypto are advocates of privacy. Facebook is no champion of privacy and many people will not use it.

Thanks jadedjack. One more question. Just for scientific purposes I would like to run it on Amazon's c4.8xlarge which has 36 vCPU's (2.9 GHz Haswell processor), 60 GB RAM and an ECU of 132. Does this make sense and how can I be sure the program uses all these ressources to 100% (CPU, RAM,...)? It would be interesting, how fast it can find an address with 10 characters for example.

I tried that for jadedjack  
I ran it for a few days without success.

What i did was to run several instances of the genacc program. And monitored the cpu and memory use with htop

I didn't run them in the background with nohup. I used the utility "screen" that creates virtual terminals.
https://www.howtoforge.com/linux_screen

I think there were 16 or so running before the cpus were maxed out.

Amazon also has GPU instances, it would be interesting to see if the java code could be modified to use a GPU.

I will leave here if someone buys my 48million at 50 satoshi each.

If you are serious post your offer here

Which EC2 did you use? The c4.8xlarge?

I'm not sure. I think so. It was the most powerful I saw at the time. I talked to "A Man", he says it might be possible to port the program to use a GPU. It would probably be a LOT faster then.

[jadedjack]

Maybe, yes. What about the code? Is it completely open source on github? And how can it be safe, that no one can reverse engeneering the generated private key, if he knows the address? Is it impossible?

The source is included in the zip file.

Here is an interesting article on crypto keys

I can't answer that well, but all the developers used went out of their way to use vanity gens for their accounts, so that gives me confidence.   

I know that a public key is calculated from a private key, and then in a 2nd step the account number is calculated from a public key.  All this is done with heavy duty cryptography.  So, it is just my guess that if you use a vanity address, it might or might not make it a little easier to reverse engineer the public address from the account address.  And if somebody does that?  so what?  It is a public address and meant to be known. 

But to reverse engineer the public address to the private address, would still be just as impossible as before. 

So, just my guess and only a guess is that a vanity key shortens the amount of time it would take one to try to crack a public address from an account number (a pointless task), but would make no difference trying to calculate a private key from a known public key, which would still be all but impossible. 

Now if somebody wanted to make a vanity private key, that I am guessing would be a security threat.

If anybody is trying to make a Bitcoin <-> NEM solution, NEM already has an awesome multisig feature set built in.  And in the future we will have mobile apps that will be able to work effectively as 2FA device that isn't relying on a third party service or third party software, but instead is all blockchain based.

But what about the on the BTC end?  Lots and lots of people have had security breach after security breach, and it has really seriously hurt BTC.  

Good news for BTC, I just read about a new solution for a $200 device.  http://techcrunch.com/2015/05/04/case-is-an-insanely-secure-hardware-bitcoin-wallet/ and that is a lot of money for sure, but for a business, this looks like the way to go.  Even for a regular person with a lot of BTC and using it often, it looks good.

But of course when the NEM mobile app comes out and adds support for a fingerprint scanning on your mobile, you will be getting they same level of security as that $200 device, but for free, and with no third party.

Most of the code has been open sourced, not all.
The core is open source.
I  hope remaining parts will be released soon.

Nothing is impossible  but with current technology getting the private key out of the public one will cost you much more than XEM market cap

[gimre]

Please keep the personal attacks out of here. Im sorry I want results.

I want jelly starfish.

[yshin365new]

Wow!
NEM's public interest score is 8th.
Same with NXT.
